DOOR CONSTRUCTION.

Be it known that I, CARL J. Jnoxsoma subject of Norway, residing at Superior, 1n

the county of Douglas and State of Wisco sin, have invented certain new and useful Im rovements in Door Constructions, of whlch the following is a specification.

The invention relates to closure constructions, especially to Window constructions in which a movable piece of glass is provided in association with a screen element, whereby when the glass element is moved to permit ventilation the o ening will be closed by the screen. In t e present particular embodiment, the device is adapted to use in doors, and its simplicity and adaptability to that use is an important advantage of the invention.- It is an especial aim of the invention to rovide a device of this character which will e peculiarly eiiicient in effecting the assage of flies outwardly through a win ow or door opening. To this end, it is an aim to'provide a means whereby the upper edge of the glass will be presented at the lower part of an opening in such a manner that iiies ali hting upon the inner side of the glass will e free to crawl completely to the upper 'edge thereof and take flight therefrom from the exterior of the house.\ At the same time it is a purpose to effect the ample support of the upper ed e of the glass when the device is closed, an to rovide a good wind-tight joint between t e frame opening and the glass. In connection with this 'it is also desired to secure the screen Vin such relation to the glass that ample ventilation will be secured with*L a practical elimination of liability of in ress of iies.

It is also an aim to comp etely clear the window opening of the screen when the glass is in closed position.

An additional purpose is to provide a desirable. construction 1n a door for the uses indicated.

I am aware that screens have been connected to the up r edge 'of window sash elements or the l1 e in such a manner that when the gJlass is in lowered osition the, screen will e drawn downward Vand when raised the screen will be move above the opening, and I do not claim broadly this idea, except wherein parts are constructed or associated in the same relation as hereinafter claimed.

Additional objects, advantages and features of invention will appear in thel con- Bpeeleetion of Letten Patent.

the mounting of the There is illustrated a door 10, adapted to i be mounted in any ordinary door frame and to be provided with the usual lock and knob construction, the last named details not being illustrated, as forming no peculiar part of such invention. Thedoor 10 in the present instance comprises the stiles 11 of simple form at each side, rectangular in cross sectlon, between which the top and bottom rails 12 and 13 are mounted. Casin portions 15 and 14 are mounted on the oregoing` parts, at the inner and outer sides of the door respectively, forming a suitable space 'within the door for a sliding sash element 16 to be described. The sash 16 comprises a bottom piece 17, and two uprights 18 of similar form and construction, these three parts being suitably grooved on the inner' sides to receive a pane of glass 19 which sto s short of the upper end of the4 uprig ts 18 a considerab e distance, the measure of which depends upon the manner 1n which the door 1s to be used. The groove for the glass is located nearest to the front side of the door, leaving a considerable por? tion of the sash frame pro'ecting toward the inner side of thedoor. the height of the sash frame, suitable springntermediately ot' pressed pins 20 are mounted having end ortions projecting outwardly from the sas in.

each direction to engage alternative in a series of'openings 21 formed in the stl es 11, and if Ldesired a groove 22 may also formed in the-Stiles next adjaeentthe sash be .m

and alined with thepins 20 so that it is not I necessary for the pins to be completely retract/ed in order to free the sash for vertical adjustment. The pins 2 0 have handle ortions 23 projected inwardly before the g ass, and suitabl formed to be used to draw the pins and a vSo to serve as handles to move the sash. The upper ends of the uprights 18 of the sash' are' formed in any .suitable man. 'ner with a kerf 24, extending a distance below the upperedge of the glass before mentioned, and the ker extends approximately in a plane parallel to the glass and close to the inner side of the sash, so that the kerf is spaced approximately one-half inch from the glass. et in the kerf there is a portion of screen material 25 snugly engaged betweenthe nprignts 18, being rectangular in form, and having its u per and lateral edges dush with the ends an sides of the uprights 18, While its lower edge extends horizontally, being; engaged to the full inner ends of the korf 211 before mentioned. The screen is preferably cut so that the woven edge 26 will e presented downwardly, reducing the liability of the raying of the screen. The screen -is utilized to hold the sash frame in proper form after engagement of the glass therein, and is secured in place by engaging a number of screws 27 through the material of the u rights 18, centrally thereof at the inner si e, the-screws bein slidablein the inner material beside the erf, and snuglvH so that its opposite side Iportions bear against the opposite sides of the screen, the upper edge of which is set snugly in the fold of the metal. Itis undesirable that this metal edging be located at the lower edge ofthe screen,

` glass,at times, and crawl upon the inner side to as it would teiid to induce files to leave the of the screen, from which they would tend to pass into the house. In Aeach casingportion a window opening'29 is formed, having a vertical dimension considerably less than sli the vertical dimension of the space between the top and bottom rails of the door, and

preferably less infwidth than the space be- Atween the u rights 18 of the sash. The glass 19' is Loi a eight'slightly greaterthan the hei ht of tl'ieopening 29, so that whenthe g sash is in its uppermost position, lwitlr'tlie bottom 17 immediately under the opening 29, ther-glass willextend above the upper side of theopening. The frame 16 is o such siz'e Athat when4 in the last men- 'tioned position the uprights 18 extend into close relation with. the top rail 12 of the door. One of the recesses 2l in each stile of the door is at such a level as to engage a respective pin 20 to hold the sash in this raised position. In the present instance, the space within the door is such that when the sashl is at the lower limit of its movement the screen 25 extends slightly above the opening 29, although this is not absolutely essential as the recess 22 may be suitably positioned in the Stiles of the door to engage the pins 2O to hold the sash in' proper position when lowered. The grooves 22 may also be utilized as a limiting means and the pins constructed so that they cannot be fully withdrawn at both sides, in any well known way. In the upper part of the door,

upon the inner side of the casing section 14, there is provided a guard piece 31, of a width to fit snugly between the uprights 18 ofthe sash, and having a suiicient thickness to engage closely against the outer side of the screen 25, or very close thereto as found most desirable. The lower edge of the element 31 is grooved to receive the upper edge of the glass 19 snugly therein, and a small projection may be formed above this groove, as at 32 to engage in the glass holding grooves of the uprights 18 to form a snug joint around the glass, preventing ingress of air in objectionable quantities, when the sash 16 is raised.

With .this device satisfactory ventilation may be obtained through doors while closed, and the device operates as atrap means, at least to the extent o f permitting ready escape' of flies alighting upon the glass when they follow their natural tendency to crawl upwardly toward light, and in having an opposing effect upon flies without the door, since flies do not tend to crawl downwardly into dark places. `The space 33 between the upper edge of the glass 19 and the lower edge portion of the screen 25 maybe termed a slot. When the sash 16 is in closed position, should there be any flies upon the screen 25, these will be caused by the piece 3l to take Hight from the screen through the upper part of the opening 29 as the sash is *,iai'sed, untilv the .opening is closed by the *glass 19.

It will be seen ,that a very simple construction of closure and fly guard is providedv adapted-to be manufactured at a low cost and used readily by the general public without diliculty.

`In theevent that the glass 19 becomes broken, in order to replace it with a new piece, the casing piece 14n or 15 is removed,

@the sliding sash taken out, and the screws 27 removed at one side, after which a piece of glass ada ted to fit snugly in the grooves of Athe uprig ts' 18 when in parallel relation, the

broken pieces of glass removed and the new pane slippedinto place. The screen is then drawn taut again .and the loosened screws secured in place to holdthescreen taut, and the parts replaced in proper order.
